SPECIFICATION forming part of Letters Patent No. 591,295, dated October5, 1897.

i nate filed ma 25', 1896. Serial No. 593,054. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES W. REEVES and CHARLES W.LENTZ, citizens ofthe United States, residing at Columbus, in the county of Franklin andState of Ohio, have invented certain new and useful Improvements inClothes-Wringers, of which the following is a specification.

Our invention relates to improvements in clothes-wringers; anditconsists inthe constructions and combinations of parts hereinafterdescribed, and set forth in the claim.

In the accompanying drawings, Figure l is a side elevation of a wringerembodying our invention with some of the parts broken away. Fig. 2 is aplan view of the same. Fig. 3 is an end elevation showing a part of theframe and some of the operating devices located therein. Fig. 4 isadetail view in section, taken on the line y y in Fig. 1. Fig. 5 is adetail view of the bearing-supports and spring connection for one of therolls. Fig. 6 is a transverse sectional view on the linear; w in Fig. 7is a front view of the housing or gear-shield.

I Like parts are represented by similar letters of reference in theseveral views.

In the said drawings, a and a represent the usual compressing-rollsconstructed with rubber or elastic peripheries in the usual manner.These rolls are each provided at each end with projecting tru'nnions 0.a j ournaled in suitable bearings supported on the main frame, one ofthe trunnions a being extended" and having secured thereto a handled, to

which the power to drive the rolls is applied.

The main frame consists, essentially, of four connected partsviz. sidestandards I) b,- a connecting-arch 1), connecting said standards at thetop, and a connecting-bar 17 which connects said standards at thebottom, said bar b being adapted to form the usual drainboard. The upperpart of each of the side standards I) b is formed 'of a semicylindricalshape in cross-section and is surmounted at the top with a lug orprojection 6 by means of which it is attached to one end of the arch b,the respective ends of the arch being bifurcated, as shown at b, toreceive the same, a fastening-bolt b being extended through the parts tofasten them securely together.

cured to the tub or other receptacle.

The lower part of each of the side standards I) b is ofiset andprojected downwardly to form a leg b which constitutes one side of theclamp by means of which the frame is se- The other side of the clamp bis pivoted, asshown .at 6 to the standard I), and has a hearing I)", inwhich the trunnion a of the lower roll is seated, so that a downwardpressure of the rolls causes the part b to approach the'part b and thusfirmly clamp the tub or other receptacle when pressure is placed on therolls, as hereinafter more fully specified.

The upper portion of each of the standards I) is adapted to form ahousing and guide forthe supporting-head orbearingsupport c for theupper roll. These bearing-supports 0 have in-the lower end a bearing 0,in which the trunnion a is journaled. They also are provided withlaterally-extending lugs 0 which fit in the cylindrical portion of theside frames 1) and form guides for the vertical movement of the upperroll. Each of the heads c is furtherprovided with upwardlyextendinghook-shaped lugs 0 adapted toengageand hold the end of thepressure-spring d. This spring 61 is in general outline of thesemielliptical type, and instead of being curved throughout its lengthit is formed at the center with a flat portion d, and in contact withthis fiat portion d thereis a fiat head d formed on the bottom of anadjusting-screw (1 which is adapted to be adjusted in avertically-moving head 01, sliding in a socket 01 formed in the arch 1).Above the socket d the arch is bifurcated, as shown at d, and there ispivoted in this bifurcated portion a cam-lever d adapted when turned onits pivotal center to come in contact with the top of the head 61 andthus produce more or less pressure on the spring d.

The rolls a are caused to rotate together by intermeshing gears e e,secured to the journal at each end of said rolls. These gears are placedon the inside of the frame and are covered and protected by a housing 6which fits over said gears and serves as a shield, which housing orshield has a slotted opening 6 which extends from the bottom of thehousing upwardly, so that the said housing may be placed over therespective roll-shafts or journals from the top, and when so placed willhang freely on the upper roll-shaft, thus insuring perfect freedom inthe respective parts. Each of the housings e is further provided with alaterally-projecting lip a which extends outwardly alongthe rolls a anda and presents a narrow edge against which the clothes contact inpassing through, so as to more fully protect them from dirt or grease.

By the arrangement described we place the bearings for the rolls at theextreme ends of the trunnions and have the intermeshing gears betweenthe said bearings and the ends of the compressing-rolls.

By having the fiat bearing-surfaces on the spring and theadjusting-screw, respectively, a more even pressure on the respectiveends of the rolls is secured, which is transmitted to the rolls at theextreme ends of the trunnions, so that a more even and uniform pressurein the lengths of the rolls is secured than when the gears are placed onthe outside and the bearing-supports placed next to the ends of therubber rolls.

By having the arch Z) of a single piece, which is preferably made ofmalleable iron, and having the bifurcated portions, as described, aframe of extreme simplicity is secured which is very strong and notliable to become disarranged or out of adjustment.

The standards being semicircular in the main body and open at thebottom, the upper roll is allowed a free adjustment within saidstandards, so that the clamping parts I) b will be adapted to operate onany thickness of tub or other device to which they are to be secured. Itwill be understood that as the spring is compressed the rolls will beforced downwardly, so that the clamping part b", turning on its pivotalbearing 11 will tightly engage the part to which it is to be clamped,and any additional pressure caused by the separating of the rolls inoperation will create an additional clamping pressure on the tub orother receptacle.

Having thus described our invention, we claim In a wringer thecombination with side standards having downwardly-p roj ectin g legs andbearing-guides, an arch constructed in a single piece and formed at eachend to engage lugs on said standards, said arch being provided at thecenter with a socket and a bifurcated portion, an adjusting-screw andclamping-lever in said socket and bifurcated portion respectively, anupper roll having bearings fitted in the bearing-guides of saidstandards, a lower roll journaled in hinged legs pivoted to saidstandards, a spring over the upper roll, a fiat head on the adjustingscrew and an opposing flat bearing-surface on the springsubstantially as and for the purpose specified.

In testimony whereof we have hereunto set our hands this 29th day ofFebruary, A. D. 1896.
